Pompey bring their Checkatrade Trophy group stage campaign to a close at Charlton on Tuesday evening.
But it is the hosts – who have already qualified for the knockout stages – who are the 23/20 favourites with Sky Bet to secure all three points.
The Blues will join them if they can triumph at The Valley and can be backed at 9/4, with the draw at 5/2.
Kenny Jackett’s side have been short on goals in recent weeks, so a 1-0 win might seem a good option at 10/1.
You can also take a punt on them securing the victory after trailing at the interval at a mammoth 33/1.
Brett Pitman is the 9/2 favourite to net the opener, but he might not be the best bet with Pompey set to make changes.
Conor Chaplin at 13/2 could be an attractive option, while Kal Naismith, Milan Lalkovic and Danny Rose are available at 8/1, 12/1 and 16/1 respectively.
Those with a more long-term view, however, could be taking a look at the 20/1 on offer for the Blues lifting the trophy at Wembley in April.
